Solubility of Hydrogen, Carbon Monoxide and 1-Decene in Water, Toluene and Water-N-methyl-2-pyrrolidone Biphasic Solvent Mixtures

Abstract

The solubility of carbon monoxide and hydrogen has been determined experimentally as a function of their pressure in toluene, water and water-N-methyl-2-pyrrolidone (70:30 v/v) mixtures in the 383-403 K temperature range. The value of Henry’s constant for hydrogen and carbon monoxide was determined in all three solvent systems. Pressure had a linear influence on all systems, as predicted by Henry’s law. Through experimentation, the solubility of 1-decene in the organic and aqueous phase was established. The experimental data for the liquid-liquid equilibrium of 1-decene in a toluene and water-N-methyl-2-pyrrolidone mixture has been evaluated in the temperature range of 383-403 K. Temperature has a negligible effect on 1-decene solubility in the aqueous phase, but a significant effect in water-N-methyl-2-pyrrolidone (70:30 v/v) combination. The study of the solubility of hydrogen and carbon monoxide in organic and water-N-methyl-2-pyrrolidone mixture can be used for the kinetic study.
